paraffinic long-chain aliphatic hydrocarbon or wax-like material
결론
- The 2918 cm-1 absorption is consistent with alkyl/CH2 antisymmetric C-H stretching [1].
- The 1462 cm-1 band is directly supported as a paraffin-associated feature, consistent with methylene deformation in a wax-like saturated chain [1].
- The 2849 cm-1 band is consistent with CH2 symmetric stretching in alkyl C-H groups [2].
